DETACHABLE MOUIHPIECE FOR PIPE-STEMS.

Specification of Letters Patent.

Application filed August 27, 1908.

Patented July 6, 1909.

Serial No. 450,482.

To all whom it may concern:

Be it known that I, ROY L. REED, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Detachable Mouthpieces for Pipe-Stems, of which the following is a specification.

This invention relates to detachable mouth pieces for pipe stems, and has for an object to provide means whereby stems of the pipes may be conveniently supplied with new mouth pieces at a minimum figure thus obviating supplying a pipe with an entirely new stem as a substitute for a worn stem.

Other objects and advantages will be apparent as the nature of the invention is better disclosed, and it will be understood that changes within the scope of the claim may be made without departing from the spirit of the invention.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views,Figure 1 is a side view of a pipe showing the application of the present invention thereto, parts of the pipe being in section. Fig. 2 is a perspective view of the coupling member.

Referrin now more particularly to the drawing, t ere is shown a pipe 1 of usual form provided with a bowl 2 and a stem 3. The stem 3 is provided with a rectangular passage 4 which communicates with the bore 5 formed in the stem, and this rectangular passage is adapted to receive a correspondingly shaped portion 6 of a coupling member 7. The coupling member is preferably formed from aluminum or sheet metal and the walls 8 and 9 respectively, of the said coupling member are extended outwardly of the remaining walls of the coupling member to provide wings 10 and 11 respectively, which are curved or flared from each other, as shown. A mouth piece or bit 12 is provided, and this bit, has formed therein a rectangular passage 13 to receive a portion of the coupling member 7, and forwardly of the passage 13 the bit or mouth piece is provided with curved recesses 14 which terminate in shoulders 15. The passage 13 communicates with the usual passage 16 formed in the said bit or mouth piece. I

In assembling the coupling member and the stem and mouth piece it may be stated that the Wings 10 and 1 1 of the said coupling member are inserted in the bit or mouth piece and it is obvious that these wings which are normally curved as described will tend to assume their normal position and will spring into the recesses formed in the bit or mouth piece. The remaining squared portion of the coupling member is finally inserted in the passage 4 formed in the stem 8 and the va rious elements described are effectively held in a convenient manner to each other. Upon reference to Fig. 1 of the drawing, it will be seen that the squared portion of the coupling member spans the line of the division between the bit or mouth piece and the stem to prevent leakage as is obvious.

A device as herein set forth and described is extremely simplein construction, may be manufactured at a relatively low figure and is such that a pipe may be quickly supplied with a new mouth piece or bit at a minimum figure.

I claim:

In a pipe, a stem provided with a longitudinally extending bore, and having a rectangular passage at one end communicating with the bore, a bit having a passage communicating with the passage formed in the stem and provided with oppositely curved recesses, a coupling member connecting the bit with the stem and comprising a rectangular hollow body having a portion in the rectangular passage formed in the stem, and oppositely directed curved wings carried by said hollow body and engaged in the curved recesses formed in said bit.

In testimony whereof I aflix my signature in presence of two witnesses.

ROY L. REED.
